Chocolate Mousse Cheesecake Steals the Show.
This is one of my favorite desserts to make for a special occasion because I can make it in advance, and everyone raves about it! It’s as beautiful as it is delicious and I can’t wait for you to try it! Talk about a triple threat with three layers of decadence in every bite.
I first shared this recipe in 2017, adapted from Mel’s Kitchen Cafe’s cheesecake “pie” version. As we’ve enjoyed it over the years I’ve adapted it to bake as a traditional cheesecake in a springform pan, which we prefer, with higher cheesecake to mousse ratio.
How to make Chocolate Mousse Cheesecake:
Oreo Crust: Add whole Oreo cookies to a food processor and pulse until very fine crumbs. Stir in the melted butter. Pour mixture into a 9-inch springform pan. Use the back of a measuring spoon to press it firmly into the bottom and half way up the sides of the pan. Refrigerate while you make the cheesecake filling.

Cheesecake: Cream together the softened cream cheese and granulated sugar until well blended. Add the eggs, egg yolk, and vanilla and mix. Blend in the sour cream. Spread the filling over the Oreo cookie crust in an even layer.
Bake at 325 degrees F for 45-60 minutes, or until the edges are set and the center is slightly firm (it may jiggle just slightly). Remove from oven and allow to cool completely. (No need to bake in a water-bath, since we will add a mousse and ganache on top).

Mousse: Add chocolate chips to a heatproof bowl. Heat ½ cup cream in a microwave safe bowl until hot. Pour cream over chocolate chips, and set aside for a few minutes, to allow the chocolate to warm. Then stir until smooth. Allow to cool completely.
Add remaining ½ cream and vanilla to a bowl and whisk until stiff peaks. Gently fold in to chocolate mixture. Spread the mousse over the top of the cooled cheesecake. Refrigerate for at least 3-4 hours, or overnight.

Ganache: Place chocolate chips in a small bowl. Add butter and cream to a saucepan over medium heat, Bring to a simmer. Pour the hot cream mixture over the chocolate and stir until melted and smooth. Stir in vanilla and powdered sugar. Pour the ganache over the chilled cheesecake. Refrigerate for at least an hour before serving

Make Ahead and Storage Instructions:
To Make Ahead: his cheesecake has a few different steps, so consider making some ahead. The Oreo crust can be made days in advance, stored in the fridge. Bake the cheesecake layer one day, cover, and refrigerate then continue with the mousse and ganache the next day.
To Store: Keep any leftovers covered in the refrigerator for 1-3 days.

Hello, I noticed that there are no egg yolks in your mousse. Is this correct?
Yes, correct. Hope you enjoy the cheesecake!
I would like to make this recipe, however, could someone please clarify the amount of ingredients and process for the mousse? The ingredients says 2 Large semi dark chocolate chips, I am guessing there is a measurement missing here? And also 90gm of vanilla extract seems a bit too much? It’s also not added in the method process. Thanks, I look forward to trying it.
Hi Angela, sorry the automatic Metric conversion on this recipe is not working properly. I’ve added the metric measurements for you, if you refer to those in parentheses next to each ingredient amount. Enjoy!
A few steps, but worth it in the end. Will definitely make again!
Hi I’ve made this pie and it is delicious. Thank you for your wonderful recipe. Would you know if it freezes well? Thanks again
Made this yesterday/ today in a springform pan and it turned out so pretty! My first taste test was very good 🙂
